Question

Evaluate the function rule for the given value
y = 4 x 2^x for x= -6

Answer 1

\(\large y=4(2^x)\)?

Answer 2

Is that the problem?

Answer 3

y= 4 times 2 to the power of x

Answer 4

out of these:
1/8
1/32
-48
1/16

by "/" i mean a fraction

Answer 5

ok, so \[\large y=4(2^{(-6)})\]\[\large y=4*\frac{1}{2^{6}}\]\[\large 2^{6}= 64\]\[\large y=4*\frac{1}{64}\]simplify and you'll have your answer

Answer 6

you can rewrite \[\large 2^{-6} \to \frac{1}{2^6}\]

Answer 7

1/8?

Answer 8

how many times does 4 go into 64?
